Requires the energy facility site evaluation council to review the status of pipeline utility corridor capacity and distribution for petroleum in the southwest region of the state. In conducting this study, the council shall, at a minimum, review the following: (1) Whether pipeline utility corridor constraints exist, and if so, to what extent;

(2) Whether there is adequate pipeline utility corridor capacity in the state to meet existing demand; and

(3) Whether the current pipeline utility corridor system is expected to meet projected demand growth in the southwest region of the state.

Authorizes the council to also examine pipeline utility corridor capacity and distribution in other areas of the state to the extent that it has an impact on supply to southwest Washington.

Requires the council to submit its findings and recommendations to the legislature by December 1, 2007.
